Updated: Amazon Releases Kindle Fire Update; New Features In iOS Apps

Amazon (NSDQ: AMZN) has released its promised Kindle Fire software update, which the company says will resolve some of the problems users have been experiencing. Update: The company also updated its Kinde iOS apps.

The update “enhances fluidity and performance, improves touch navigation responsiveness, gives you the option to choose which items display on the carousel, and adds the ability to add a password lock on Wi-Fi access. The update will be automatically delivered to your Kindle Fire.”

The Kindle Fire has received a spate of poor reviews recently, notably one from usability expert Jakob Nielsen, who called the device “disappointingly poor.” By releasing the update before Christmas, Amazon has the chance to fend off some returned Fires received as holiday gifts.

David Pogue tested the Kindle Fire with the update and says it “erases the stubbornness that characterized the original Fire software….Today’s touch-ups make an enormous difference.”

So far, the Fire seems to be selling well despite some bad reviews. Amazon recently reported that it is selling upwards of 1 million Kindle devices a week, though it didn’t break out sales by type (Fire vs. e-ink reader).

Update: Amazon also added new features to its Kindle iOS apps. Kindle for iPad users can now access all the magazines and newspapers in the Kindle Fire newsstand. The Kindle iPad app now supports print replica textboks, and all the iOS apps got a new PDF reader. Users can also e-mail documents to their Kindle e-mail addresses and access the documents from the iOS apps.
